Hi Andrew,
It is a long time ago that I did this bit so my memory is a little hazy but
the pins are not actually a tight fit and the bushes themselves are quite
short. I have worked with a number of builders through this phase and none
have had a problem. To be quite honest none of them have really raised any
questions, they followed the instructions in the manual and all worked OK.
It is good that you have thought through and anticipated problems but in
this instance it probably seems worse than it is.

alignment bushes
Hi Pete,
Thanks for that response. It is good to know that the drilled holes
are predetermined for the correct angle. My concern actually arose
---From reading others' posting that the the pins were difficult to
engage, which I assumed came from small twists during the angle
setting process. These are long bolts, so I suspect even a fraction of
a degree rotation would cause the holes to become misaligned. If I
could somehow verify using some reference points inside the cockpit
module that the bushes I am about to bond are actually at the correct
angle, that would be a great relief.
